Hi Marzipan,
qRules has a function for querying SharePoint lists, called FilterOwssrv. If you can see the version info in a SharePoint list, you can query it via qRules.
You might also want to look at DBXL which has much more extensive version support than SharePoint and allows you to list version information as well as query for old version data. Qdabra provides a free DBXL trial for download and qRules has special commands in it to make the experience even richer for codeless forms (disclaimer: Qdabra is the sponsor of this free forum). Let us know if you need help.
Hoping your almond paste is as sweet as you like it,
